The Frazer Mennonite Church (Mennonite Church USA) is an outgrowth of Diamond Rock in an early Amish settlement two miles north of Malvern, Chester County, Pennsylvania. The Weaverland Missions Committee in 1908-1909 revived this work, and the first service was held on 1 May 1910. In 1917-1918 a frame church was built along the Lincoln Highway, west of Malvern. The 1955 membership, many of non-Mennonite extraction, was 115; Mahlon Witmer had the bishop oversight, Marcus Swanenberg, Milton G. Brackbill, and C. Ralph Malin were the ministers, and Irvin J. King the deacon.

The congregation celebrated its 100th anniversary with a special service on 9 May 2010, and a Bible school reunion was held on 12 June 2010. A major celebration was held on the weekend of 15-17 October 2010.

On 20 April 2013, Frazer Mennonite Church was released from membership in the Lancaster Mennonite Conference and became an associate member of the Atlantic Coast Conference. The congregation had expressed "preliminary affirmation" for a general membership statement that "welcomes into membership all persons who profess faith in Christ and all who desire to walk with Christ in order to grow and trust in God, in following the light of Scripture and in living Jesus’ way," without naming or singling out gays for exclusion. The congregation requested membership in the Atlantic Coast Conference after it became clear that Lancaster Mennonite Conference would not support the church's position.
